BUTTON-SETTING INSTRUMENT.

SPECIFICATION forming part of Letters Patent No. 353,818, dated December'7, 1886,

Application filed February 9, 1886.

To all whom it may concern:

Be it known that I. FRANCIS H. Rrcnnnns, a citizen of theUnited States,residing at Springfield, in the county of Hampden. State ofMassachusetts. have invented certain new and useful Improvements inButton-Setting Instruments, of which the followingisa specification.

This invention relates to improvements in hand-instruments for attachingbutto us to fab- 1o ric or leather by means of malleablepointed metallicfasteners, the object being to provide an instrument of that class inwhich the fasteners shall be automatically fedto the driverchannel froma magazine within the instru- Inent.

To this end the invention consists in the combinations hereinafterdescribed and claimed.

In the drawings accompanying and forming a part of this specification,Figure l is a top View of a button-setting instrument embodying myimprovements. Fig. 2 is a side elevation of the same. Fig. 3 is a topview of the lower left-hand part of the instrument, showing the slide,slide-case, and the front end of the magazine. Fig. 4. is a longitudinalvertical section through theinstrumcnt, showing the parts in positionready for operation. Fig. 5 is a front view of the instrument as seenfrom the left hand in Figs. 1, 2, and 3. Fig. 6 is a similar viewshowing some of the parts situated at the close of the settingoperation. Fig. 7 is a bottom view, showing from the under side the sameparts as shown in Fig. 3. Fig. 8 is a cross-section in line a a of the 5handle containing the fastener magazine. Figs. 9, 10, 11, and 12 aresectional views showing four successive stages of the opera tion offeeding a fastener from the magazine into the driver-channel. Figs. 13and 14. are similar views showing two stages of the fastener-settingoperation. Fig. 15 is a side elevation, partially in section, showingthe magazine-cover drawn back preparatory to replenishing the supply offasteners. Fig. 16 is a section of the magazine with the cover removed.Fig. 17 is a perspective view of the magazine-follower. Fig. 18 is asimilar view of the slide-case, showing the interior thereof. Fig. 19 isa perspective view of the front part of the slide. Fig. 20 is a similarview of the Serial No. 191,362. (No model.)

back part of the-slide, showing the front surface thereof. Fig. 2l is asimilar View of the driver, showing the rear surfaces thereof. Figs. 22and 23 are respectively perspective views of the fastener-feeding pawland of the transfer-spring.

Similar characters designate like parts in all the figures.

The frame-work of the instrument (designated by A) comprises a handle,H, forming the principal part of the fastener-magazine, and any suitableprojecting armas, for instance, Bcarrying the setting-die and itsoperating devices. For convenience in constructing and assembling theparts, said arm is preferably divided, substantially as shown, to form aspace for the reception of the parts carried by the arm. Said partsconsist of the sliding setting-die D, a handle, O, pivoted at 2, andsome device so connecting said handle and die that a downward movementof the one will produce a like movement of the other. For this purpose Ihave devised an arrangement of gearing, as follows: Rack-teeth 3 areformed on the back side of the die, which teeth mesh withsimilarly-shaped teeth 4. on one side of the intermediate gear, G, whichis pivoted at 5 to the arm B. The opposite side of gear G has teeth 6,arranged spirally to its axis, and meshing with the teeth 7 of acorrespond- 8o ing spiral or eccentric segment, 8, formed on handle 0.\Vith this arrangement of gearing, the eccentricity thereof being in theright direction, as shown, a regular and uniform movement of the handleimparts a movement of decreasing velocity to the die, thereby gaining inpower near the close of the setting operation, and thus better utilizingthe stroke of handle 0 than would otherwise be the case. A spring, 9, isarranged to raise the handle 0, 0 and through this the setting-die.

In another application, No. 181,383, filed October 30, 1885, for animprovement in pliers,

I have described and claimed a combination of devices adapted to besubstituted for the aforesaid gearing for similarly operating thesetting-die in my present instrument. In this case, however, thesetting-die may be carried on the swinging arm, (therein designated byB.)

The magazine is an inverted-T-shaped 10o passes, as at 21, Fig. 15.

groove formed partly in the handle H and partly in its sliding cover R.The shape of the groove may, however, be modified to suit the fasteners,for the setting of which the instrument may be in any particular casemore especially designed. In the present instance said instrument isconstructed for setting the fastener thatis described and claimed inUnited States Patent No. 314,684, granted to' Eleazer Kempshall, March31, 1885, one of which fasteners (designated byF) is shown in side viewin Fig. 8, and a row of them (designated by the same character) in Figs.4, 9, 10, 11, 12, 13, 14, and 15. The shape of the groove is shownpartlyin solid and partly in dotted lines at V, Fig. 16. On the upperside it opens into a parallel cylindrical hole or channel inclosing themagazine-spring 11 and the follower 12, which serves to push forward thefasteners F in groove V. Said follower has a short extension, 13, whichprojects down through the groove V into a groove, 15, formed in theupper side of the cover B. This groove 15 does not extend quite to theforward end of said cover, but terminates at ashort stop, 16, Figs. 13to 15, by which means the follower is drawn back with the cover, whenthis is slid off, as in Fig. 15,'to open the magazine. This operation ofcourse compresses spring 11 against the plug 17, which stops up the rearend of channel 10. It will be noticed that cover R has in this instancea hook, 18, provided as a convenient means for operating said cover. Itis also my intention to use a spring-catch (not shown) for temporarilyretaining said cover in its open position.

It will be noticed that the method of fitting cover R to frame A is thecommon one of forming tongues on one part, which fit in grooves formedin the other, as fully shown in Fig. 8. This construction is notessential, but is adopted.

merely because it is convenient to make.

At its front end the frame A has a front plate, 20, extending below themagazine, and through which the T-shaped magazinegroove To this frontplate the sides 22 23 of the slide-case L are respectively secured byrivets (not shown) or by screws. The slide (designated by N) consists ina front part, 24, and a rear part, 25. These two parts, secured togetherby rivet 26, comprise but a single operative slide, which might just aswell be constructed integrally were its shape such that it could inpractice he so manufactured. The driver 30 stands in the space betweenthe two parts of slide N, being held from vertical movement by somesuitable connection with slide-case L. This connection is preferablymade as follows: On the inner side of walls 22 and 23 are formed thegrooves 27 27, into which are fitted the corresponding lugs, 28 28, Fig.21, formed on the edges of the driver. By means of this construction thedriver is firmly held, yet allowed to adjust itself laterally to theadjacent parts-an important consideration. The lower end of the driver31, Fig. 21, serves as a stop against the short projection 32 on slidepart 24, to limit the upward stroke of said driver to its posithefasteners F are then forced by the follower against the thin part orblade 36, and immediately above ledge 37 Fig. 21, of said driver,"

as shown in Figs. 4, 9, 12, and 15. Said ledge has a width closelyapproximating the thickness of one fastener, as 38, Fig. 15, andtheslide part 25 has a thickness similarly corresponding to one ormorein the present instance to two-of them. The space between the upperend of slide part 24 and the raised surface 42 and slide part25 is thedriver-channel 44, through which space the fastener is, driven upagainstthesetting-die;

For the purpose of transferring fasteners from above ledge 37 to abovethe driver-point 49, slide part 25 is provided with a fastenerfeedingpawl, 41, and with a transfer-spring, 45, both of which are readily madeof wire, as

shown in Figs. 22 and 23. The pawl is conspring in another recess, 47,both formed in the slide part 25. g The operation of these parts isfully illustrated in Figs.9 to 12. SlideNand the accompanying part areshown at rest in their normal positions in Fig. 9, fastener 38 restingagainst thedriver-blade 36, while the fasteners 39 stand in opening 35.In Fig. 10 the slide is moved down to its lowest posit-ion, carryingfasteners 39 down between the lower end of the driver and front plate,20, and the point of pawl 41 into notch 40, below fastener 38, which inthe meantime has remained .on ledge 37, and now rests there under spring45. In Fig. 11 the slide has moved up about twothirds of the distancetoward its first position. The pawl 41 has pushed up fastener 38, whosepointhas been thrown forward by spring 45 into driverchannel 44. On thecompletion of understood from the drawings and preceding description. Inusing the instrument the fabric or other material,50, is properly placedover the slide N and the setting-die brought down on it, as in Fig. 13.A button, 51, is then put with its shank in the cavity 52. (See Fig. 4.)
